This is an General Availability release. We did our best to eliminate bugs and problems during the testing release, but this is a software, so bugs are expected. If you encounter them, please report them to our bug tracking system.

Product suffix has been added to the Percona XtraDB Clusterrpm packages, which means that packages have been renamed from Percona-XtraDB-Cluster-server to Percona-XtraDB-Cluster-server-55. Bug fixed #1255616.

When installing first Percona-XtraDB-Cluster-client and then Percona-XtraDB-Cluster-server on two single statements or a single statement with both packages , yum would install percona-xtrabackup-20 instead percona-xtrabackup package as dependency of Percona-XtraDB-Cluster-server. Bug fixed #1226185.

If SELECTFORUPDATE... query was aborted due to multi-master conflict, the client wouldn’t get back the deadlock error. From client perspective the transaction would be successful. Bug fixed #1187739.

Temporary tables are not replicated, but any DDL on those tables were (in this case it was TRUNCATE), which would generates error messages on other nodes. Bug fixed #1194156.

When setting the gcache.size to a larger value than the default 128M, the mysql service command did not allow enough time for the file to be preallocated. Bug fixed #1207500.

CREATETABLEASSELECT would fail with explicit temporary tables, when binlogging was enabled and autocommit was set to 0. Bug fixed #1240098.

Write set flags defined in wsrep API are now exposed to application side appliers too. Bug fixed #1247402.

initstop script on CentOS didn’t wait for the server to be fully stopped. This would cause unsuccessful server restart because the start action would fail because the daemon would still be running. Bug fixed #1254153.

Because some package names have been changed with the product suffix and and additional dependencies being added please check the manual before starting new installations. Debian users are requested to use apt-getdist-upgrade or apt-getinstall for upgrade, for more refer to installation guide.
